It is now starting to look easier to start from scratch by building a new LF RX or simply to continue using the external preamp. 73 Joe VO1NA Hello Joe,maybe is less work to build an up-convertor to HF and use the existing RX at HF. Using a widely available (and thus cheap) 10MHz xtal you end up right in the 30m band (10.137kHz). As the RX is probably very sensitive at 10MHz maybe you can do without any amplification at LF, just a bandpass filter and a mixer (preferably passive DBM, minicircuits has some nice and cheap building blocks). 73, Rik ON7YD |
